title: 'vntrs: Variable Neighborhood Trust Region Search'
version: 0.2.1
doi: 10.32614/CRAN.package.vntrs
abstract: Implements the variable neighborhood trust region search (VNTRS) algorithm
  for nonlinear global optimization, following Bierlaire et al. (2009) "A Heuristic
  for Nonlinear Global Optimization" <https://doi.org/10.1287/ijoc.1090.0343>. The
  method combines neighborhood exploration with a trust-region framework to search
  the solution space efficiently. It can terminate a local search early when the iterates
  converge toward a previously visited local optimum or when further improvement within
  the current region is unlikely. The algorithm can also be used to identify multiple
  local optima.
